Single-Frame Image Super-Resolution

Super-resolution refers to the process of creating a higher-resolution image with finer details, by utilizing the information of a single low-resolution image or multiple low-resolution ones taken from almost the same scene. Single-frame super-resolution is essentially a task of interpolating between the pixels in the original single-frame image. After a comprehensive bibliographic study of the existing super-resolution techniques, several of the most efficient of these techniques are selected. Also a new implementation, based on a tree data structure is presented.
